MODELLING AND SIMULATION ON VELOCITY AND PERMEABILITY TO PREDICT BACILLUS ON LAG PHASE IN PREDOMINANT LATERITIC AND SILTY FORMATION IN COASTAL ABONNEMA, NIGER DELTA OF NIGERIA

The deposition and migration process of bacillus lag phase condition has been of paramount interest due it challenges in ground water quality, this study mathematically analyze the migration process base on lag behaviour the contaminant express in some formations, the study develop a model that express the migration process and its behaviour between lateritic and silty formation, the developed model simulated generated theoretical values, it has shows the level of lag found to be insignificant as the rate of permeability and velocity of flow influences the level of lag in the formation, the simulated results were thoroughly compared with experimental values, both parameters developed a faviourable fits, the validation of the developed model will definitely made the developed concept a useful tools to experts.
